Ifremer and their partners organized a workshop in Le Quartz, Brest, France, from Wednesday 20th to Friday 22nd October 2004, during SeaTechWeek 2004. The aim of the seminar was to assess the state of the art as to conditions of occurrence of waves or groups of waves of unexpected severity, responsible for ship wrecks and damages to offshore oil and gas production systems; and to establish a ``road map'' as to research actions and collaborations needed to improve the prediction and forecasting abilities in this domain.

This page gives access to the presentations that were made during the workshop, and to the full papers that the authors provided after the workshop. The presentations are available as pdf files that may be viewed with the Acrobat Reader freely downloadable software. For most of the presentations, the original Powerpoint is also made available (PPT or PPS).
